I'd appreciate some help with this code, either what's wrong with it or even a better way to do it. Here's what I have for writing to the event log: private void WriteToEventLog(string message) { string cs = "QualityDocHandler"; EventLog elog = new EventLog(); if (!EventLog.SourceExists(cs)) { EventLog.CreateEventSource(cs, cs); } elog.Source = to event log cs; elog.EnableRaisingEvents = true; elog.WriteEntry(message); } And here's where I'm trying to call it: private readonly Random _rng = new Random(); private const string _chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; private string RandomString(int size) { try { char[] buffer = new char[size]; for (int i = 0; i < size; i++) { buffer[i] = _chars[_rng.Next(_chars.Length)]; } return new string(buffer); } catch (Exception e) { WriteToEventLog(e.ToString()); return null; } } c# event-log share|improve this question asked Jul 15 '09 at 19:12 PushCode 1,42941726 what line is the error on? –NikolaiDante Jul 15 '09 at 19:13 please provide a stack trace –Brad Barker Jul 15 '09 at 19:16 "Object reference not set to an instance of an object" - means that you are referencing a NULL, it is much more helpful to know the line of code where this happens, because then you can see what it is that is NULL that you're referencing. –Stan R. Jul 15 '09 at 19:17 All I have is this: Error loading and running event receiver QualityDocHandler.DocumentHandler in QualityDocHandler, Version=1.0.0.0, Culture=neutral, PublicKeyToken=e33ce5caa212a16d. Additional information is below. : Object reference not set to an instance of an object. ...this is running on a SharePoint site so I don't see the stack trace.
